Hi,

 

I try to exchange datas  between host and Guest  by adding these lines in a guest .xml conf file :

 

<channel type='pty'>

      <target type='virtio' name='arbitrary.virtio.serial.port.name'/>

      <address type='virtio-serial' controller='0' bus='0' port='1'/>

    </channel>

 

 

Then  /dev/virtio-ports/arbitrary.virtio.serial.port.name is exposed in the guest and a /dev/pts/x  is seen as source path on the host.

 

I checked that on two Linux hosts :

 

1)

 

libvirt-daemon-driver-qemu-1.2.8-16.el7_1.3.x86_64

qemu-kvm-1.5.3-86.el7_1.5.x86_64

qemu-kvm-common-1.5.3-86.el7_1.5.x86_64

qemu-guest-agent-2.1.0-4.el7.x86_64

ipxe-roms-qemu-20130517-6.gitc4bce43.el7.noarch

qemu-img-1.5.3-86.el7_1.5.x86_64

Linux sparring 3.10.0-229.el7.x86_64 #1 SMP Thu Jan 29 18:37:38 EST 2015 x86_64 x86_64 x86_64 GNU/Linux

 

 

2)

 

qemu-img-0.12.1.2-2.415.el6.x86_64

qemu-kvm-0.12.1.2-2.415.el6.x86_64

gpxe-roms-qemu-0.9.7-6.10.el6.noarch

 

 

Linux orion 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux

 

 

 

The device is only exposed on the guest of the first host .

 

Is it due to a too old version of qemu and/or Linux  on the second host  or some packages  missing on this second host ?

 

Thx.

 

Regards,
